GOLF-BALL.

SPECIFICATION forming part of Letters Patent No. 710,750, dated October7, 1902.

Application filed July 30, 1902, Serial No. 117,604 (No model.)

To all whom, it may concern: 7'

Be it known that I, RICHARD B. CAVANAGH, a citizen of the United States,residing in \Vashington, in the District of Cl umbia,have

invented certain new and useful Improvements in Golf-Balls, of which thefollowing is a specification. p

This invention relates to golfballs and its object is to reduce the costand improve the 0 durability and other qualities of the balls.

Some of the golf-balls now in use are so lively that they meet withdisfavor with many players, since it is impossible to make accurate putsand approaches.

My improved ball combines the feature of exceedingly low price anddurability and avoids the disadvantage of being too lively for a shortgame, while well adapted for a long flight when given a heavy blow.

The accompanying drawing shows one form of golf-ball made in accordancewith my improvements.

For a center piece A, I employ hard rigid material, preferably hardwood, although asbcstos or asphalt or other suitable substance may beemployed. This center piece I inclose in asphere B of moderate size andconsisting of sawdust, ground cork, or other comminuted material mixedwith a compound of glue or glycerin or any other suitable viscous orcolloid mixture. This sphere is preferably formed under great pressure,so that the comminuted material is compressed and the whole sphere ishighly compacted. If desired, the

sphere B may be compressed into the form of half-shells and then appliedto the center pieceAand subjected to further compression.

The comminuted material is indicated at B and the cement at B.

The sphere B, I inclose in a relatively thin spherical layer C ofhighly-compressed paperpulp similar to that employed in the manufactureof car-wheels or lincrusta-ware. This material is very durable andspringy and contributes to the flight of a ball.

Upon the layer C, I apply a shell D, composed of a mixture similar oranalogous to that employed for the shell I and the whole is inclosed ina cover E of gutta-percha, which preferably holds the filling of theball in a state of compression.

It will be seen that the spheres B and D taken together form a thicklayer or sphere, which is provided with a lining or inlaid layer 0 ofrelatively stiff hard material, whereby undue disturbance of eitherlayer B or D under a blow is prevented, and hence undue distortion ofthe filling and cover is avoided. The comminuted material and the gluecompound 1 are sufficiently springy to enable the ball to make a longflight undera heavy blow, while the ball is comparatively dead under alight blow, thereby meeting the requirements of the game.

Variations may be resorted to within the scope of my improvements. I

Having described my invention, I claim-- 1. A golf-ball comprisingspheres of comminuted material, mixed with an adherent substance, animperforate layer of hard ma- 7o terial separating said spheres, and ahard cover.

2. A golf-ball comprising spheres of compressed comminuted material,mixed with an adherent substance, an imperforate layer of compressedhard springy material separating said spheres, and a cover ofgutta-percha.

3. A golf-ball comprising spheres of comminuted material mixed withadherent material, an imperforate layer of hard springy 8o materialseparating said spheres, and a hard cover.

4. A golf-ball comprising spheres of comminuted material mixed with acompound of glue and glycerin, an imperforate layer of hard materialseparating said spheres, and a hard cover.

5. A golf-ball comprising spheres of comminuted compressed cork, animperforate layer of hard, springy material separating go said spheres,and a cover of gutta-percha.

6. A golf-ball comprising a hard center piece, a layer thereon ofcomminuted material, a layer of paper upon said comminuted material, alayer of comminuted material 5 upon said paper, and a cover of plasticmaterial.

7. A golf-ball comprising a hard center piece, a layer of comminutedmaterial mixed with adherent material, a layer of paper upon saidcommiuuted material mixed with adherent material, a layer of comminutedmaterial upon said paper, and a cover of plastic ma terial.

S. A golf-ball comprising a hard center piece, a layer thereon ofcompressed comminuted material mixed with glue, a layer of paper uponsaid comminuted material, a layer upon said paper consisting ofcomminuted material mixed with glue, and a guttapercha cover.

9. A golfball comprising a hard center piece, a layer thereon ofcompressed comminuted material mixed With a compound of glue andglycerin, a layer of paper upon said comminuted material, a layer uponsaid paper consisting of comminuted material mixed with a compound ofglue and glycerin, and a gutta-percha cover.

10. A playing ball comprising a relatively thin layer of compressedpaper and two relatively thick spheres of softer springy materialseparated by said paper layer.

11. A playing-ball comprising an imperforate layer of compressed paperand two spheres of softer springy material separated by said paperlayer.

12. A golf-ball comprising a sphere of compressed comminuted cork mixedwith a compound of glue and glycerin, and a covering of compressed guttapercha holding said sphere under compression.

13. A golf-ball comprising a plurality of spheres of comminutedmaterial, a layer of hard material separating said spheres, and a coverof compressed plastic material holding said spheres under compression.

14. A golf-ball comprising a plurality of spheres of compressedcomminuted material,

a layer of compressed hard springy material separating said spheres, anda cover of compressed gutta-percha holding said spheres undercompression. 7

15. A golf-ball comprising a plurality of spheres of comminuted materialmixed with adherent material, a layer of hard material separating saidspheres, and a cover of plastic material holding said spheres undercompression.

16. A golf-ball comprising a hard center piece, a layer thereon ofcompressed comminuted material, a layer of compressed paper upon saidcomminuted material, a layer of compressed comminuted material upon saidpaper, and a cover of compressed plastic material holding saidcomminuted material under compression.

17. A golf-ball comprising a hard center piece, a layer thereon ofcompressed comminuted material mixed with glue, a layer of compressedpaper upon said comminuted material, a layer upon said paper consistingof compressed comminuted material mixed with glue, and a gutta-perchacover holding said layers under compression.

18. A golf-ball comprising a hard center piece, a layer thereon ofcompressed comminuted material mixed with a compound of glue andglycerin, a layer of compressed paper upon said comminuted material, alayer upon said paper consisting of compressed comminuted material mixedwith a compound of glue and glycerin, and a compressed gu ttaperchacover holding said layers under compression.
